Which bitumen emulsion properties must be continuously monitored during production to avoid batch rejection?

[Salvi]

Critical online or frequent checks include soap solution pH, temperatures of bitumen and water phase, feed rates to the mill, density trend, and viscosity trend. For cationic grades, particle charge and pH are especially important. Sieve and stability tests are often done per batch or at defined intervals. Monitoring also includes tank level and agitation status to prevent separation. The goal is to detect drift early, because small deviations in pH, temperature, or shear can quickly push the emulsion toward instability and rejection during storage or delivery.
